Robert C. Kern, MD, Professor and Chair, Department of Otolaryngology-Head and Neck Surgery, Professor, Medicine-Allergy-Immunology, Northwestern University, Feinberg School of Medicine, Chicago, IL, presented on the following topics: Definition of CRS, Current Treatment Paradigms, Pathogenesis, Theories of Etiology, and Future Treatments.

The goals of this program are to improve outcomes and increase awareness of the etiology, pathogenesis, and epidemiology of chronic rhinosinusitis (CRS) and to develop applications for future treatment. After hearing and assimilating this program, the clinician will be better able to:

1. Explain the current theories about etiology and pathogenesis of CRS.
2. Recognize how variable combinations of environmental and host factors can lead to the development and exacerbation of CRS.
3. Describe epidemiologic and epigenetic contributions to the development of CRS.
4. Adjust the timing, frequency and aggressiveness of surgical intervention for CRS in order to avoid overuse of antibiotics and mitigate local immune response.
5. Consider the implications of current hypotheses of etiology and pathogenesis on future therapies.

The original programs were presented by Robert C. Kern, MD, Professor and Chair, Department of Otolaryngology-Head and Neck Surgery, Professor, Medicine-Allergy-Immunology, Northwestern University, Feinberg School of Medicine, Chicago, IL
